Java将word转换为文本

复制代码

在Java中，你可以使用Apache POI库来读取Word文档并提取文本内容。你可以在 Maven 项目中添加以下依赖：

复制代码

<!-- Apache POI for Word 2007+ (.docx) -->
<dependency>
	<groupId>org.apache.poi</groupId>
	<artifactId>poi</artifactId>
	<version>4.1.2</version>
</dependency>
<dependency>
	<groupId>org.apache.poi</groupId>
	<artifactId>poi-ooxml</artifactId>
	<version>4.1.2</version>
</dependency>

<!-- Apache POI for Word 97-2003 (.doc) -->
<dependency>
	<groupId>org.apache.poi</groupId>
	<artifactId>poi-scratchpad</artifactId>
	<version>4.1.2</version>
</dependency>

以下是一个简单的示例代码，展示如何使用Apache POI将Word文档转换为文本：

复制代码

import lombok.extern.slf4j.Slf4j;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.extractor.WordExtractor;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.springframework.web.multipart.MultipartFile;

import java.io.IOException;

@Slf4j
public class WordUtils {

    /**
     * Word转换为文本
     *
     * @param file Word文件
     * @return 提取的文本
     */
    public static String wordToTextConverter(MultipartFile file) {
        try {
            if (file.getOriginalFilename().endsWith(".doc")) {
                // 处理Word 97-2003文档
                return processOldWordDocument(file);
            } else if (file.getOriginalFilename().endsWith(".docx")) {
                // 处理Word 2007及以上文档
                return processNewWordDocument(file);
            } else {
                throw new RuntimeException("不支持的Word文档格式");
            }
        } catch (IOException e) {
            throw new RuntimeException("无法读取Word文档", e);
        }
    }

    private static String processOldWordDocument(MultipartFile file) throws IOException {
        try (HWPFDocument document = new HWPFDocument(file.getInputStream())) {
            WordExtractor extractor = new WordExtractor(document);
            String text = extractor.getText();
            log.info("Word文档内容: {}", text);
            return text;
        }
    }

    private static String processNewWordDocument(MultipartFile file) throws IOException {
        try (XWPFDocument document = new XWPFDocument(file.getInputStream())) {
            if (document.getParagraphs().isEmpty()) {
                throw new RuntimeException("Word文档为空");
            }
            XWPFWordExtractor extractor = new XWPFWordExtractor(document);
            String text = extractor.getText();
            log.info("Word文档内容: {}", text);
            return text;
        }
    }
}
